Macedonian scabious

Sun

Full sun; light afternoon shade is useful in very hot climates, but too much shade encourages floppy stems.

Water

Water regularly while establishing. Once established, water during prolonged dry spells; avoid persistently wet soil.

Soil

Well-drained, moderately fertile soil, including sandy, chalky or gravelly ground. Avoid waterlogged clay and heavily enriched soil.

Height

2-3 ft (0.6-0.9 m)

Spread

1-2 ft (0.3-0.6 m)

Flowers

Early summer into autumn, with rounded, deep crimson to burgundy flower heads.

Foliage

Green to grey-green, slightly hairy leaves form a basal clump; leaves higher on the stems are more deeply divided. Usually dies back in winter.

Growth

Moderate; often flowers in its first growing season from young plants.

Growth rate

Moderate

• Water newly planted clumps when the soil begins to dry, until roots are established.
• Avoid routine heavy feeding; rich soil produces loose growth that is more likely to flop.
• Use a light gravel mulch where winter damp is a problem, keeping the crown uncovered.
• Support stems with twiggy branches or a discreet plant ring before flowering if the site is exposed.
• Remove unwanted seedlings while small, or leave a few to replace ageing plants.

Pruning. Remove spent flower stems regularly to prolong flowering, leaving a few seed heads if you want seedlings. Cut dead stems back to the basal foliage in late winter or early spring.

Early spring

Remove dead stems and check that the crown has not become buried under wet mulch.

Spring

Plant in a sunny, freely drained position and water while establishing.

Late spring

Add discreet supports before the flowering stems become tall.

Summer

Deadhead regularly and water during extended drought.

Late summer

Leave selected flower heads to ripen if you want seed or replacement seedlings.

Autumn

Remove unwanted seedlings and clear fallen leaves away from the crown on damp sites.

• Thread through sunny mixed borders so the small burgundy flowers appear to float among neighbouring plants.
• Combine with ornamental grasses for a loose, meadow-like planting with contrasting flower and seed-head shapes.
• Plant beside catmint or perennial salvias for a long-flowering purple-and-burgundy combination.
• Use in gravel gardens with yarrow and other sun-loving perennials where drainage is sharp.

Garden styles it suits: Cottage garden, English country, New perennial (prairie), Pollinator garden, Dry gravel garden and Wildlife garden.

Plant it with: Catmint, Perennial salvia, Yarrow, Feather reed grass, Gaura and Globe thistle.

Wildlife: The open flower heads provide nectar and pollen for bees, butterflies and other flower-visiting insects over a long season.

• Flopping stems: provide full sun, avoid rich feeding and support the stems early.
• Crown or root rot in wet soil: improve drainage or move the plant to a raised bed; do not keep the crown wet.
• Powdery mildew: improve airflow, avoid overcrowding and water the soil rather than repeatedly wetting the leaves.
• Aphids on young shoots: wash small colonies off with water and encourage natural predators.

Not known to be toxic to cats, dogs, horses or people. No particular plant part is recognised as poisonous, although species-specific toxicity information is limited and it should not be treated as an edible plant.

• Sweet scabious (Scabiosa atropurpurea)

  Its flowers usually have more conspicuous enlarged outer florets and prominent pale-tipped stamens. It is commonly grown as an annual or short-lived perennial and comes in a wider range of colours.

• Caucasian scabious (Scabiosa caucasica)

  Its flower heads are larger and flatter, usually lavender-blue or white, with a broad ring of enlarged outer florets rather than small, rounded burgundy heads.

• Field scabious (Knautia arvensis)

  It normally has pale lilac flower heads with more noticeably enlarged outer florets, rather than the deep crimson, more evenly rounded heads of Macedonian scabious.

The botanical epithet macedonica refers to Macedonia, part of the plant's native Balkan range.

Propagation. Sow seed in containers in spring or autumn; seedlings may vary in flower colour and habit. Divide healthy young clumps in spring, keeping roots attached to each section. Self-sown seedlings can be moved while small.

Accepted botanical name
